Look at this set of 10 numbers:
78 81 60 75 83 65 60 50
18 90
-Which value would change the most if the number 20 replaced the number 50 in the set?
-mean
-median
-mode

first arrange the given data in ascending order. then find the mean, median and mode.
mean=sum of the given numbers/n
median=n/2th data.
n-number of data
mode is the data that occurs many times. Can u find the mean, mode and median for the given set of data? @Laken

after finding those for the given data, replace the number with 20 and again find the mode, mean and median. then compare the results. that will help u to figure out which of them changes most. if u find any difficulties while working pls ask. i will help u:)
